Afflicted

The Afflicted are humanoid races who have been gifted abilities or "afflicted" by the Daedric Prince, Peryite, in Skyrim. Afflicted have the ability to vomit a green substance that is extremely acidic. It appears that Peryite "afflicted" them so that they could "cleanse all of Tamriel" by spreading this affliction. They can be found in the dwemer ruins of Bthardamz, due west of Dragontooth Crater.
